We study the nonlinear electronic transport properties of a ballistic quantum ring. We analyze the I-V symmetry properties with respect to inversion of an external magnetic field up to third order in the bias. While the linear conductance follows the Onsager relations and the first nonlinear correction do not, we find that the next order term is system specific.
